[0002] When processing the existing speed reducer gearbox, it is necessary to clamp the gear and tighten it, then put the gear into the gearbox and rotate it to install the gear in the gearbox. However, currently, when clamping the gear in the gearbox, only specific gears can be clamped, and different gears cannot be clamped according to the gear size. The "Fixture for Processing a Speed Reducer Gearbox" disclosed in the application number "CN202222685994.8" is also an increasingly mature technology. By rotating the turntable forward, the rotating rod drives the winding wheel to rotate, the pulling rope pulls the moving plate upward, and the two rubber clamping plates approach each other, so that the rubber clamping plates can clamp and fix the rotating shaft of the gear. Through the cooperation of multiple groups of teeth and the limiting mechanism, the rotating shafts of different gears can be clamped and fixed. However, this device still has the following defects: when processing the gearbox, when placing gears at different positions, it is necessary to manually adjust the placement angle of the gear. Currently, the position of the gearbox is fixed, which is not convenient for adjusting the inclination angle of the gearbox to facilitate gear installation.
